[math-fun] something linguistic

I’m looking for couples of english words starting with ‘w’ that are pronounced in the same way, even written the same, but: the first is like “wh*” and the other “w*”. Bad examples: “were” and “where” do not qualify because the first “e” is pronounced differently “witch” and “which” do not qualify because of the extraneous “t” Motivation: in norther parts of England, the “wh” seems to be pronounced as “chw”, in a way similar to swedish “sj” or “sk”. That would mean that such pronounciation is the original one, and current BBC-english pronounciation is a ‘degradation’. Any perfect examples? I know this is not math, but some on this mailing list like word games and language fun too. (hé Bill?) Wouter.
